Abstract
Remarkable nanoscopic changes were observed in-situ in metastable oxide particles on the room temperature stage of a TEM under as electron beam intensity of 10 19 e/cm 2sec. Particles of 10–15 nm diameter α-Al 2O 3 and 5nm diameter Al metal were obtained from 100nm metastable θ-Al 2O 3 particles by a process dependent on the electron beam intensity. Al nanoparticles were bonded by continuous irradiation via surface diffusion of Al atom and the formation of 2 nm sized Al clusters The effects of the electron beam are the irradiation induced increase of the oxygen mobility and localized heating.
